Hello everyone! We are currently developing a membership management system, which requires the use of RF readers to read and write non-contact IC cards. Multiple card machines are connected in parallel. Now I want some product interface functions, examples, and demo programs. The key is to know how to To achieve multi-machine networking applications (how to accept data according to the machine number when sending data), are there any products that can meet the requirements? Are interface functions supported? Please heroes with development experience show the way !!!!

??? Use 485 interface to connect multiple terminals in parallel. Please recommend any type of terminal equipment. These devices must have programming interfaces, including interface functions, examples, demo programs, etc.
